Platinum palladium

[SeanL]

Could this be platinum or palladium ?
I found it in a glass jar hidde n in an old shed.

Properties so far.

Non magnetic.
Bubbles in hydrogen peroxide.
Continuity when tested with multimetre

Thats the only tests i can do at home.
Do these metals form naturally like this

Cool. Hopefully this will assist (even in a little way) some of the knowledgable folks around these parts.

I hope so.
There are no bullion dealers around to have checked with xrf machine. And also im a little reluctant to go incase it just a shattered cog or machinery part and i get a wierd look.
Its just strange to store it in a little jar and hidden away.... maybe just wishful thinking

Could be RHODIUM

Density or specific gravity would be a good attribute.

It looks like hematite.

looks a lot like a shot catalyst used in very old flue gas chemical reactions. As non magnetic maybe manganese / molybdenum although looks too metallic for that. ( which would also account for the hydrogen bubbles in peroxide). Got access to aqua regia and a blow torch? flame test to rule those out.
